I have a 1988 k5 blazer that had a 700r4 in it. This is the 3rd 700r4 my truck has eaten so I am going to put a SM465 4speed into my truck. My only dilemma is figuring out all the combinations that are possible with this tranny with the spline outputs and inputs of the transfer case. I have a NP205 I am planning to use on this tranny. It is the older version with the figure 8-bolt pattern. Now my NP205 has a 27 input and it has the 27spline slip yoke conversion on it already. Now I was reading up on these trannys and transfer cases. I understand that there is a long and a short shaft on the SM465. I know that there was a 10 spline short I believe that was originally bolted to a NP205 with a 10spline input or a 27-spline input. I know that the SM465 also has a 35spline on the 2wd version so this transmission. Now I also have heard that is has a 32-spline 4wd output witch went into the NP208's and new style NP205 with the circler bolt pattern. I heard that the 10-spline shafts wear out excessively on the SM465 output and or input on the NP205. Now I from what I believe there is a 4wd SM465 with a 32spline output is this true. And is there a 32spline input I could get for the late model NP205 to get it to work with the SM465 so they both utilize a 32spline shaft. I understand that ORD has the 32spline short and the 32 spline long input shafts for the 205. Can I get a SM465 and a late model NP205 to both have 32 spline shafts? I believe that would be the strongest and would last the longest am I correct? Where can I find a kit or what parts would I need to get the SM465 to have a 32spline 4wd output that would work on a late model NP205 with a 32spline input. And I also believe the input for the NP205 32 spline is a female am I correct? If anyone can please help me on figuring this puzzle out I would really appreciate it. Also if I were to find a SM465 with a 10spline output what shaft is 4wd, short or long? And would that hold up if I were to mate the 10spline SM465 output and the 27spline input for the 205 with a 10 to 27spline coupler sleeve. Also what adapters would I have to use for what. I would like to use the stock GM cast iron SM465 to NP205 Adapter if possible. Can someone please help me out?
